Mute Swan (Cygnus olor)
Mute Swan Description: Introduced to North America from Europe in the mid-1800s to decorate country parks and large estates. The first wild mute swans were introduced to MI in 1919 in Charlevoix County. The population of MI was about 15,500 in 2010.
Identification: Adults are only swans with orange beaks and black buttons on their beaks, on their necks turning into an "S". Adults are 55 to 63 in (140 to 160 cm) long and have a wingspan of 79 to 94 in (200 to 240 cm). Males weigh 24-26 pounds while females weigh 19-20 pounds, making them one of the heaviest flying birds. Bright and colorful. Young birds are unclean, and their beaks are gray.

Reproduction: reproduce at age 3 and stay with the same mate for life. The territory has an area of 4-10 acres, the nests are large (4 feet by 4 feet). An average of 4-6 eggs are laid in 3-4 depressions in the middle of the nest and incubated by the female for 36-38 days. They have a lifespan of 20 to 30 years.
Impact and damage: Dangerous to humans (very strong), they hunt marine animals and other wild animals and their bad behavior, they destroy marine habitats by consuming 4- 8 pounds of wood per day which is a staple food for native birds and cover. for native fish and invertebrates. Similar species: Trumpeter Swan (Cygnus buccinator) has an all-black beak and is native; The Tundra Swan (Cygnus columbianus) is small, black-billed, and indigenous.
Monitoring and rapid response: Destruction of eggs and nests; kept alive and euthanized by veterinary medicine; the capture and respiration of organic carbon dioxide; life arrest and euthanasia injection; Live retention and cervical dislocation; to ensure Alpha chlorosis; one shot to the head with an approved, licensed device.
